create PHP script that creates test files and uploads them into hotfolders and calculates current import time

Background information: We run a digital asset management system (called Elvis DAM). To import new files we use hotfolders. New files are uploaded into a hotfolder via FTP and are then automatically imported into the system whilst having metadata added to them in the process. Problem is: These hotfolders get clogged sometimes. If too many files are imported at a given time by too many users it may take many hours to import them. Normally it takes about 10minutes for a file to get through from start to finish. If there is a large backlog this time increases sharply. Currently we have no way of knowing in advance how long it may take to import the files as there is no reporting available. For a drawing of the process pls refer to "current Hotfolder [login to view URL]" YOUR JOB Find a way to calculate and display the current time it takes to import files via the hotfolders. suggested solution (however we are open to other ways of solving the problem): You to create a PHP script that tracks test files whilst they are imported: 1. start with a small, uniquely named text file, for instance „[login to view URL]“ (the number at the beginning is required in order to be accepted by the hotfolder) 2. encode current date and time into the file name (or find other ways to take note of the current time and link that to a file), for example: 9783551580733_hftest_2013-11-22T14:14:[login to view URL] 3. upload the file about every 30min into the hotfolder (via FTP) 4. check in Elvis DAM via Rest API which files have arrived and compare their imported-into-Elvis timestamp against date and time as noted in the filename 5. Display the time difference for the latest file on screen (=current hotfolder processing time) - pls refer to "skribble Elvis hotfolder processing [login to view URL]" 6. send out an email to a specified address if average importing time exceeds 4h. 7. optional: write the current hotfolder processing time into a MYSQL table for statistical purpose repeat this continously We provide: Webserver with PHP and mysql (if required) Hotfolder FTP login Elvis DAM Rest API login Elvis DAM API documentation: [login to view URL] GitHub repository Also part of the job The source code will be open sourced You to upload the source code into a GitHub repository keep login credentials in a separate file (don’t upload into the GitHub repository)
